Hi, I am using AMCL package for localization on my robot. I am not sure about what the "InitialPose" topic does. Is it just the initial pose of the robot at the start when we dont have good localization (if yes then do we need to publish it continuously?). Or is it the initial pose that it uses in every iteration to generate new particles (this doesn't make sense since it already has the base_link-->odom and map-->odom transforms). Thank you.
